What a joke! A restaurant that encompasses a whole block made expectations high. However upon being seated and having a short, squatty ketchup bottle plopped down on the table (half full btw), we should have gotten up and left.
The servers were less than cordial or professional. In an hour we saw our waitress 3 times. (took the order, delivered food, gave the check)
The food was all wrong. Having been to Germany and eaten in many German restaurants in Europe, I expected a hell of a lot more than Denny's-style food with a German name.
Perhaps if you go to Rheinlander's and Gustab's pub, the best thing is to get smashed on bier first before you proceed to order any food! Anything would taste good after drinking out of a 3ft stein.
